Sr. Data Scientist/Machine Learning Engineer

Start Date: December 1st or January (manager does not want anyone to start in mid-December due to the holidays) Duration: 6 months with the opportunity to extend Location: Washington, D.C., New York is preferred so a candidate may come onsite as needed, but remote is an option for the right candidate Reason for opening: backfill Interview Process: Three rounds of Zoom interviews We are looking for a

hands-on Data Scientist / Machine Learning Engineer

with a strong technical background and deep experience in working with large datasets and advanced modeling techniques. This is an

individual contributor

role within a small team (3-4 people), focused on

research, development, and implementation of machine learning algorithms

to support various business initiatives.

Key Qualifications

Strong technical and programming skills;

Python

and

SQL

required,

R

is a plus. Experience with

advanced machine learning techniques , such as:

Causal ML Forecasting LSTM / Neural Networks Transformers / LLaMA / other large language models Not just basic models like propensity scoring

Solid experience (5+ years) working with

large datasets

and building production-level models. Strong experience with

hands-on coding ; this is

not

a strategic or managerial role. Comfortable with

independent research , staying current on machine learning trends and tools. Should be able to

evaluate and assemble libraries/codebases

into usable solutions for the team. Experience

migrating platforms

(e.g., to Databricks and Salesforce) and improving dashboards and visualizations. Familiarity with

Metalearners

or willingness to research and work with them. Must have a degree in a

quantitative field : Data Science, Engineering, Statistics, Mathematics, etc.

MBAs or Business Analytics degrees are not a fit

for this role.

Client/stakeholder management is

not the primary focus . Interview Tips

Ask candidates to

walk through a machine learning algorithm end-to-end

as applied to a real business problem.

How did they choose the algorithm? Did they utilize forums, libraries, or research? How did they evaluate its effectiveness (both technically and in business terms)?
